T 0 all whom it may concern Be it known that I, FnLicn FRANCESCOLARIVEI, a subject of the King of Italy, residing at Bath, in theKingdom of England, have invented new and useful. Improvements inMachinery for Dyeing and Treating Textiles, of which the following is aspecification.

This invention relates to improvements in machines for dyeing orotherwise treating hanks ofyarns, slubbing and other textiles, in whichthe material undergoes the desired treatment immersed in the liquor. Theobject of the invention is to provide an effective mechanical meanswhich, besides causes the material to be raised off the sticks by suddenfalling contact with the liquor, whereby acomplete uniformity oftreatment is obtained. 7

According to the present invention a frame, suspended in a dye vat andcarrying the hanks of fibre or the like either on sticks, rollers or ina closed perforated cage, and partly immersed in the liquor and partlyout, is first mechanically reciprocated up and down, the

upward movement taking place at a different speed than the downwardmovement, and then the motion is changed so that the said frame or cageis longitudinally reciprocated to and fro in the vat, incontradistinction to such machines in which the hank carrying frameremains stationary immersed in the liquor, or is moved uniformly and8111111]:

taneously in both vertical and horizontaldirections. I p

The mechanism for reciprocating the frame up and down may be combinedwith means to hoist the frame clear of the vat when it is desired toremove or replace'the sticks carrying the fibre.

The invention is more particularly described with reference to theaccompanying drawings, in which Figure 1 is a plan view-of the device inone form; Fig.2 is a corresponding side elevation. V

A vat 1 of any usual form is mounted adjacent to the driving'mechanismsupported on standards 2. .A frame 3 is suspended within the vat 1 bymeans of a rope 4 passing over pulleys 5. The frame 3 is recessed at itssides as at 6, to receive the sticks 7 adapted to carry the hanksoffibre to be dyed or otherwise treated by the liquor in the vat 1. Arail 8 is adapted to lie over the depressions only.

6 to hold the sticks in position, and this rail 8 can be lockedby'meansjof'finger-pieces 9 turning on pivots l0.

When the to and fro horiZonta-l'motion is desired, pinion l3is slid intogear with the fully toothed wheel''A and the frame is connected to areciprocating connectingrod 11, by a detachable pin .12 passing throughthe bracket 13 on the frame 3 and said connecting'rod '11. Frame?) isfirst lifted to a certain level to. allow of the insertion of bearingrollers 14: on spindles 15" in bearings16 on the top of-the sides of thevat 1. A step 17 maybe'arranged' at the" side. of the vat 1 to allow ofthis operationbeing conveniently performed.

The bearingrollers 1 .1: support a 'longi- H tudinal cross rail'18having lateral brackets 19 integral with it, adapted to be connectedtoeyes 20-011 the frame 3by detachable pins 21 connected to shortchains22-on the frame to prevent accidental loss. The frame 3 can furtherybeguided in its to and fro movement by means of bars-23% fastened detachupand down reciprocation of the frame 3,

the cord 4 is attached to the peripheryof pulley 28. 1.

The difference inflspeed of the vertically reciprocating frame whenmoving. up. and

down can be obtained .by meansof gears or drums of different diameter.In a preably by set screws 24 on theside of the vat ferred arrangement,however, the high speed is obtained in one direction by allowing thedriving shaftto. rotate freely by reason ofthe weight of the frameconnected to it, so that the yarn, at the fall of the frame, is

raised off the sticks-by the maximum resist ance of the liquorcreated.by.the..extreme velocity ofv the fall. shaft 36 mounted.inbearings ,;on frame 2, is continuously rotated in one direction Onthis shaft36, which .carriesa, worm wheel 38 driven by a worm 39 on a:

For this purpose the I shaft 40 having fast and loose pulleys 41, -12,are mounted gears MC and'32. The gear 32 is toothed on a limited lengthof its periphery only. It is obvious that if pinion 43 is kept out ofgear, the shaft will rotate in one direction as long as pinion 31engages with the toothed portion of a mutilated wheel 32 causing therope f to coil itself on pulley 2S and thereby raise the frame 3; but assoon as the last tooth of the mutilated wheel disengages self frompinion 31, shaft 30 thus set free, will reverse under the weight offrame 3 and will thereby be lowered into the vat uncoiling the rope 4from pulley 28 in its fall. When the toothed portion of the continuouslyrotating wheeliiil comes again to engage with pinion 31, frame 3 isagain raised and fallsback into the vat in the same manner andthus thedifierential up and downinotion will continue as long as desired. Ifrequired,

- means maybe provided to allow the guioing of frame 3 in vat 1' up anddown, without later on interfering with the to and fro movement.

Should now it be desired to revert to the to ,and fro movement, the rope4 is disconnected from the pulley 28, the pinion 4:3 is then slid. intogear with the fully toothed pinion l4: onshaft 3,6. The shaft 30 thenrotates continuously in the same direction.

The rotation of shaft 30 is communicated to aparallel shaft 4:5 throughpinion gearing 46, 1:? The shaft as. has a-hevel wheel 48 keyed to, itwhich drives the. bevel wheel 49 on shaft 50 which carries a disc 51having a crank pin carrying the connecting rod 11,

reciprocating this, whereby the frame 8 is moved to and fro in themanner previously described.

When it is desired to remove the sticks 7 from the frame 3, or. removeframe 3 from the vat for any reason, the rope is connected to a pin onthe periphery of pulley 29 and shaft 30 .is given a rotation so that therope 4 is wound on pulley :29 and frame 3 is raised above the vat. Railscan then be slid in under the frame and this removed. To lower the framerope l is first coiled by hand round the periphery of pulley in adirection opposite to that in whichthe shaft 30 rotates, and thus whenthe machine is set in motion, shaft 30 in its rotation uncoils rope 4:,whereby the frame 3 is lowered into the vat. The rails 18 are detachablefrom the frame 3 so that they canhe used with a number of frames.

It is obvious that a single driving mechanism as shown on the stand 2can operate the movements of frames in anumher of vats, that is to saythat for instance to obtain the up and down motion, a. rope or ropes 52may pass along with or be connectedto the rope 4, to connect to therails l8 of-tlie frame working in connection with vat. Again the vat'lmay be subinto a number of compartments in each of which a frame 3 maybe arranged simultaneously or separately operated from the d ngmechanism on the stand.

, T larly if the shaft 4-5 is run alonga combination of separate vats orsubdivisions of one vat, the to and fro horizontal motion is easilyobtained by connecting each vat or each subdivision of one vat to shaft45 through similar arrangementsv of bevel wheels 48, 49, shaft 50, disc51, and rod 11.
